Module 15. Gas turbine engine

When testing an E.G.T system

  • the O.A.T is always taken into consideration.
  • the O.A.T is neglected.
  • O.A.T is only taken into consideration when over20degreesC.

Explanation

A thermocouple measures the temperature difference between its hot and cold (reference) junctions, so the cold-junction/outside-air temperature affects the reading. When testing an EGT system the OAT must always be taken into account to apply the correct cold-junction compensation and verify accuracy.
